Windows Data Execution Prevention stops Norman installation

Problem description

The Norman installation is stopped with the message "To help protect your computer, Windows has closed this program."

Solution

This problem can be circumvented by not inputing any license key and instead leaving the field blank.The installation should then continue normally. After the installation is completed and the computer has been rebooted you can add your license key by running the license wizard found at C:\Program Files\Norman\Npm\bin\licwiz.exe
